Final answer:
The potential difference, also known as voltage, between point A and point B can be found by subtracting the potential at point A from the potential at point B.
Step-by-step explanation:
The potential difference, also known as voltage, between point A and point B can be found by subtracting the potential at point A from the potential at point B. This is represented as VB - VA. The potential difference is equal to the change in potential energy divided by the charge. It is measured in volts (V).
